Flotation columns. 's Microcel™ high recovery flotation columns are establishing a new standard in flotation technology. Microcel™ flotation columns in addition to producing high concentrate grade, increase product recovery and improve plant profitability.
In this paper,a new approach has been proposed for metallurgical performance prediction in flotation columns using ANN. Furthermore, a case study is carried out in an industrial Minerals CISA flotation column (4 m in diameter and 12 m in height) at the Sarcheshmeh Copper Concentrator Plant.
Flotation column cells are flotation act as three phase settlers where particles move downwards in a hindered settling environment counter-current to a flux of rising air bubbles that are generated by spargers located near the bottom of the cell. The sparger technology is an important design choice, and allows the user to optimize the ...

On the other hand in the case of quite large bubbles, we observe this improvement only when flocs are the largest (high initial concentration of Cr). The liquid carrying away is high for the studied concentrations. 4. Flotation in pilot-scale column Tests have been performed in a pilot-scale column of 75 mm in diameter and a height of 3 m.
A unique sparger technology columns cells have established a new standard in flotation technology. For the last four decades, columns have proven their ability to produce higher concentrate grades compared with conventional mechanical flotation cells. Microcel™ columns increase product recovery and improve plant profitability.
COLUMN FLOTATION619 Кб. As another example, if insufficient column capacity has been installed, it will be difficult to operate the columns with a positive bias while still attaining target recovery.Moly upgrading profiles with flotation columns, CMP Proc. 22nd Annual Meeting, p.258 Boutin, P . 2002.
The most rapidly growing class of flotation machine is the column machine, which is, as its name implies, a vessel having a large height-to-diameter ratio (from 5 to 20) in contrast to mechanical cells. This type of machine provides a counter-current flow of air bubbles and slurry with a long contact time and plenty of wash water.

( Minerals CISA Microcel) 12m in height and 4m in diameter, each 150m3 (see Figure 1) (Massinaei et al., 2007, 2009). One of the rougher columns was chosen and operated at different operating con-ditions. The pulp=froth interface of the column was controlled using two pressure Control of Industrial Flotation Column 897
The 'Mocrocel' column Sotation developed at the ia Polytechnique and State University uses an inline mixture to generate Rne bubbles in the column. In this column, a part of the reject stream is passed throughthe inline mixture along with the frother and air to generate Rne bubbles. Figure 4 shows a dia-gram of the MicrocellTM column.
respectively. The single stage column flotation operation is composed of a Minerals CISA column with 4 m internal diameter, 12 m height and associated instruments (Fig. 3). A final product with an average grade of 28–30% Cu (chalcopyrite and chalcocite) and 0.7–0.8% Mo are obtained after flotation stages.
Flotation columns: improvement and extension of their use 1.2.2. Tests in Apirsa plant Tests were carried out with the CISA column (30 cm diameter, 7 m high) on the third Zn cleaning, and with the BRGM column (6 cm diameter, 6 m high) on Zn roughing, Cu first cleaning. The froth sampling apparatus has been tested on the Cu cleaning.
